Exploring Genomic Landscapes and Chromosomal Aberrations: Implications in Human Genetic Disorders and Infectious Disease Pathogenesis

About this Research Topic

Background

Recent advancements in genomic technologies have greatly advanced our understanding of genomic regions implicated in disease processes, including pathogenicity islands and chromosomal aberrations. Once viewed as structural anomalies or foreign elements, these genomic regions are now recognized as key modulators of of developmental processes, and disease susceptibility. Regions such as pathogenicity islands—distinct bacterial genomic segments that harbor virulence-associated genes—and chromosomal aberrations, including deletions, duplications, translocations, and inversions, are central drivers of phenotypic variability seen in various diseases.

The growing capacity to accurately map these genomic regions and analyze their impacts at high resolution offers powerful opportunities to explore genotype-phenotype relationships. Such studies can reveal novel molecular mechanisms underlying a range of medical conditions, from developmental malformations linked to chromosomal anomalies, such as ATRX syndrome, to pathogen-induced infectious diseases facilitated by horizontally acquired genomic islands. Furthermore, chromosomal aberrations are hallmarks of several hereditary and sporadic cancers, highlighting the clinical importance of comprehensive characterization of these genomic alterations.

Clarifying the biological significance of genomic islands and chromosomal aberrations provides critical insights into pathogenesis and disease susceptibility broadening the scope for the development of novel diagnostic biomarkers and tailored therapeutic strategies. Integrative genomic approaches, including comparative genomics, large-scale sequencing, transcriptomics, and bioinformatics-driven analyses, are particularly promising for furthering our understanding of these disease-associated genomic landscapes.

The goal of this Research Topic is to provide a modern perspective on the roles of genomic regions, specifically pathogenicity islands and chromosomal aberrations, in disease etiologies and pathogenesis. It aims to encourage innovative contributions detailing the mapping and functional characterization of these genomic features, highlighting genotype-phenotype correlations, identifying new disease-related mutations, and investigating interactions between host genomes and pathogenic organisms. Furthermore, this collection will emphasize how insights into these genomic factors can guide the development of improved diagnostic tools, biomarkers, and targeted therapeutic interventions.

We encourage submissions that address various aspects of genomic islands and chromosomal aberrations, focusing on their roles in diseases such as developmental malformations, cancer syndromes, and pathogen-induced pathologies. Potential themes include, but are not limited to:

• Characterization and functional analyses of pathogenicity islands in infectious pathogens.

• Mechanisms through which chromosomal aberrations contribute to developmental disorders, with a particular focus on ATRX syndrome and related chromatin remodeling conditions.

• Detailed genotype-phenotype correlation studies identifying novel pathogenic mutations and their clinical outcomes.

• Bioinformatics and computational methods for mapping and interpreting genomic islands and structural genomic aberrations in health and disease.

• The interplay between host genomic variations and microbial genomic islands in pathogen-host interactions.

• Investigations of chromosomal instability in cancer progression and its implications for precision oncology.

• Development and clinical validation of genomic biomarkers derived from chromosomal aberrations for diagnostics, prognosis, and therapeutic predictions.

• Therapeutic strategies targeting molecular pathways affected by genomic aberrations and pathogenicity islands.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?
